Estimates based on models
Preferred temperature (Ref.
123201): 15.3 - 21.7, mean 19.2 °C (based on 10 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02818 (0.01526 - 0.05207), b=3.04 (2.88 - 3.20), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.0 ±0.0 se; based on diet studies.
Generation time: 1.0 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (K=1.13).
Fishing Vulnerability (Ref.
59153): Low vulnerability (12 of 100).
Nutrients (Ref.
